APPARATUS FOR EXTRACTING OILS.

Specification of Letters Patent.

Patented Apr. 12, 1910.

Application filed September 1, 1906. Serial No. 332,956.

paratus for treating cereals, leather and other products for the purpose of extracting the oil therefrom, and drying the residue.

Theobject of the present invention is the provision of improved apparatus for treating material for the purpose of extracting oil therefrom, in which a common pipe is employed for admitting the solvent to the drum or holder containing the material and withdrawing the solvent from said drum or holder after the material has been subjected to the proper treatment, whereby the process of treating the material, withdrawing the oil and drying the resulting product may be carried on without opening the drum or holder and thereby permitting any noxious fumes or gases to escape.

A further object of the invention is the provision in an apparatus of this character of means for siphoning the solvent from the drum or holder and of means for creating a pressure within the drum or holder to facilitate said siphonic action.

Other objects of the invention will be apparent from the detailed description herein after, when read in connection with the ac companying drawings forming a part here of wherein a preferable embodiment of my invention is shown, and wherein like letters of reference refer to similar parts in the several views.

In the drawings: Figure 1 is a diagrammatic view of my improved apparatus. Fig. 2 is a longitudinal section of the drum or holder, and Fig. 3 is a section on the line 3 3 of Fig. 2.

Referring now more particularly to the drawings, A designates a drum or holder, which is preferably cylindrical in form and which is provided with the hollow spaced side walls a. The drum A is supported by trunnions B and B, which project axially from the heads thereof and are journaled in suitable bearings 13'. Any suitable means may be employed for imparting a rotary movement to the drum, but in the form illustrated in the drawing, I have shown a worm gear Z) secured to the trunnion B, with which meshes a worm Z), driven from any suitable source of power. Steam may be supplied to the interior of the hollow walls a of the drum in any suitable manner, but I prefer to use a steam pipe C, which has a loose connection with a pipe extending axially through the trunnion B and communicating with the interior of the hollow walls. The drum A is provided with a cap C of any suitable construction, through which the material to be treated is introduced into the drum. The trunnion B is hollow and extending axially therethrough is a pipe E which is rigidly supported, suitable packings being interposed between said pipe and theends of the trunnion to prevent the escape of any gases therebetween from the interior of the drum. One end of the pipe E projects within the interior of the drum A and is threaded or otherwise suitably secured in one end of a pipe union F. Extending upwardly from the pipe union F and in communication with the pipe E is a vent pipe E, the upper open end of which extends into proximity to the upper portion of the drum and terminates in a downwardly bent portion 6, so as to prevent any of the material contained in the drum from falling therein during the rotation of said drum. The opposite end of the pipe E ex tends without the drum A and is threaded or rigidly secured in any other suitable manner into a fourway pipe union F. Extending upwardly from the pipe union F and communicating with the pipe E is a pipe G, which leads to a suitable condenser G for condensing the gases and fumes withdrawn from the interior of the drum A. Communicating with the condenser G is a pump G of any suitable construction so that a partial vacuum may be formed therein to facilitate the withdrawal thereinto of the noxious fumes or gases from the interior of the drum A. Interposed in the pipe G is a valve 9 of any suitable construction for cutting off communication between the con denser and the interior of the drum A. Ex tending downwardly from the pipe union F and in communication with the pipe E is a pipe G leading to a settling basin, which may be of any suitable construction, which is adapted to receive any solid matter which may be drawn through the vent pipe with the gases.

' collecting H designates a pipe, which is smaller in diameter than the pipe E and which is concentrically disposed therein, one end of said pipe being threaded into an aperture to form in a wall within the pipe union I beyond its connection with the vent pipe E and the opposite end of said pipe extending through the pipe union F and being threaded or otherwise rigidly connected to one end of a three-way pipe union H. A suitable packing is provided between the pipe H and the pipe union F to prevent the escape of any gases therebetween. Extending upwardly from the pipe union H is a pipe I which extends to a tank I of any suitable construction for holding naphtha or other solvent, which is located in a higher plane than the drum A. Interposed in the pipe I is a valve 2' for cutting off communication between the naphtha tank and the interior of the drum. Extending downwardly from the pipe union H is a ipe J, which leads to a tank J of any suita le construction for receiving the oil and solvent from the interior of the drum. Communicating with the upper portion of the tank J is a pump J so that a partial vacuum may be formed therein to facilitate the withdrawal of the oil and solvent from the interior of the drum A. Interposed in the pipe J is a valve 7' of any suitable construction, for cutting off communication between the tank J and the drum A. Rigidly secured to the interior of the drum A diametrically opposite the trunnion B is a two-way pipe union K.

L designates a pipe, one end of which is threaded or otherwise rigidly secured to the pipe union K and the opposite end of which is journaled loosely in the aperture in the wall of the pipe union F into which the end of the pipe H is threaded, the end of said pipe extending into proximity to the end of the pipe H so as to form substantially a continuation thereof. A suitable packing is provided between the pipe L and the pipe union F to prevent the escape of the liquid therebetween.

M designates a pipe, the upper end of which is rigidly secured to the pipe union K and in communication with the pipe L and the lower end of which extends into proximity to the inner wall of the drum A and terminates in a collecting chamber M which extends transversely of the inner walls of the drum and thereacross.

In the embodiment of my invention illustrated in the drawing accompanying this specification, I have shown the collecting chamber M as consisting of a pipe, the outer end of which is closed by a suitable cap and the under side of which is provided with several rows of perforations m therein to permit the passage of the oil thereinto. To prevent the perforations m in the pipe or chamber M from becoming clogged by the material in the drum during the rotation thereof, said pipe or collecting chamber is incloscd by an arched shield of perforated metal m, which extends completely across the inner wall of the drum A and has its edges secured thereto in any suitable manner. It will be obvious that the shield m will prevent the material within the drum from coming into direct contact with the perforations m in the pipe or collecting chamber M.

The hollow side walls a of the drum A are provided with a plurality of valves (4 of any suitable construction for the purpose of admitting steam therefrom into the interior of the drum when desired.

Interposed in the pipes G and I between the valves 9 and i and their connections with the pipes E and II are arranged the pipes g and 2" which are adapted to deliver live steam to the interior of said pipe for the purpose of cleaning the vent pipe and the collecting chamber. Should the vent pipe become clogged, the valve 9 in the pipe G- closed and steam is introduced through the pipe g which will cause any solid matters or impurities contained in the vent pipe to be blown out into the interior of the drum. During this operation the valve 2' in the pipe I is open so that the steam which is blown out of the vent pipe may escape from the interior of the drum through the collect ing chamber M, pipes M, L, H and I. When it is desired to clean the collecting chamber and the pipes for effecting the withdrawal of the oil, this operation is reversed, the valves 2' in the pipe I being closed and the valve in the pipe 2" being open to permit live steam to pass to the interior of the drum through the pipe M and collecting chamber M, the valve 9 in the pipe Gr during this operation being open to permit the steam to escape from the interior of the drum by way of the vent pipe.

Having described my improved apparatus, I will now set forth the manner of using the same in treating cereals, grain or other products for the extraction of oil. The cereal, grain, or other product to be treated is intro duced into the drum A through the cover C and the cover is then securely fastened on. The valve 9 in the pipe G is then opened and the pump G is actuated to withdraw the air from the interior of the drum through the vent pipe E and cause a partial vacuum to be maintained therein. The valve 2' in the pipe I is then opened to permit solvent to flow from the tank I through the pipes I, H, L, M and collecting chamber M to the interior of the drum A, the valve in the vent line being left open to permit the gases thrown off by the solvent to escape to the condenser and to relieve the pressure in the drum. hen the solvent has risen in the drum to a point adjacent the upper end of the vent pipe E, the valve 2' is closed. The drum A is then rotated to thoroughly commingle the solvent with the material to be treated. Steam is then admitted to the hollow walls of the drum or container in sufficient quantities to thoroughly warm the material to be treated, the drum being continuously rotated. Then the material has been treated a suflicient length of time to thoroughly break the oil cells therein and to release the oil into the solvent, the rotation of the machine is stopped with the perforated collecting chamber or pipe M below the level of the liquid contained therein. The valve j in the pipe J is then opened and the drum is slowly rotated until the pipe or collecting chamber M reaches its lowermost posit-ion, when the rotation of the drum is stopped. Vith the drum in this position and the valve in the pipe J open, the oil above the pipe union L will flow by gravity through the perforations m into the collecting chamber M and from thence through the pipes M, L, H and J, into the receiving chamber J. After the level of the oil in the drum falls below the pipe union L, the remainder of the oil contained in the drum A will be drawn into the receiving chamber J, on which a vacuum is maintained by means of the pump J by a siphonic action. If desired, the withdrawal of the oil in the drum by the siphonic action may be expedited by closing the valve 9' in the vent line allowing what gases still remain in the drum to create a pressure above the oil therein, or pressure above the oil may be obtained by opening one or more of the valves a and permitting steam to pass directly from the hollow walls a into the interior of the drum. After all of the oil has been withdrawn from the interior of the drum, the valve j in the pipe J leading to the tank J is closed and the valve 9 in the vent line is open. The drum is then rotated and a full head of steam introduced into the hollow walls thereof, which will heat the material to the proper temperature. During the rotation of the drum a number of the valves (1 are open to permit live steam to pass from the interior of the hollow walls A into the material in the drum. This operation is continued until the volatile solvent, that is contained in the material being treated is removed therefrom through the vent pipe to the condenser G. lVhen the material is tested through a suitable test valve and is found to be free of any traces of the solvent, the steam valves (4 are closed to prevent the further admission of steam to the interior of the drum. Should the material then be found too moist, the machine is rotated until the surplus moisture is driven out when the lid D of the drum A is removed and the drum is inverted to permit the discharge of the material.

I do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes may be made thereto Without departing from the spirit of the invention.
